Substitute Stuart Hendrie scored four minutes from time as Basford Utd won 1-0 at Carlton Town.
Hendrie pounced after Jack Steggles parried Eugen Bopp’s cross-shot to give the visitors the points in a tight encounter at Stoke Lane.
Steggles had saved a first-half penalty from ex-Miller Ruben Wiggins-Thomas and he also made a top draw save from an earlier Hendrie effort as Basford had the better of the few chances created.
Carlton in general matched their opponents on a heavy pitch in occasional driving rain, but struggled to create openings against a defence well marshalled by the former Carlton duo of Robert Darkin and Ashley Grayson.
The loss means Carlton remain 17th in the table, 11 points clear of the relegation zone with five games to play.
The Millers are next in action on Saturday at home to Market Drayton.
